I had always waited until I had passed a speed limit sign, pulled back and held the TACC lever to reset the speed setting to the new speed limit (plus offset). Good, but sometimes I want to be slowing as I pass the sign. I tried holding the lever back BEFORE getting to the sign -- sure enough, speed stayed the same until I got to the sign, then slowed, as I had hoped. Same thing happened with increasing speed limits, it stayed at the lower speed until the higher speed sign, then sped up. Cool. Then I tried holding the lever back all the way through a small town, with a speed limit drop, then the resuming of the highway speed at the end. Lo and behold, it worked EXACTLY like the TACC with speed assist should work! My question is, is this likely to do any harm? Is there something signal overload or wear or overheating that might do damage?
